Precise chemical reagents preparation instrument

Abstract

The invention provides a precise chemical reagent compounding instrument which is applicable to chemicals, chemistries, medicines, foods, beverage, etc. which require solid-solid, solid-liquid and liquid-liquid precise compounding. The compounding instrument is characterized in that the precise chemical reagent compounding instrument comprises a liquid bell and hopper 4, a solid charging device 3 and a material selection device 2 which are arranged at the upper part of a position where a reagent bottle 5 is arranged, a temperature sensor 6 and a mixing device 8 which are arranged in the reagent bottle 5, a heating device 7 which is arranged at the bottom of the reagent bottle 5, a precision balance 9 which is arranged at the external part of the bottom of the reagent bottle 5, a PLC 10 which controls the material selection device 2, the solid charging device 3, the liquid bell and hopper 4, the temperature sensor 6, the heating device 7, the mixing device 8 and the precision balance 9. The compounding instrument of the invention has simple and convenient reagent compounding, realizes that the performance indexes such as temperature and density, etc. are fed back by query, automatic computation and data recording function, can be used in a laboratory for compounding a plurality of reagent and has the functions of recording, automatic conversion and output printing, etc., and has simple, convenient and scientific reagent compounding.

Description

Technical field: [0001] The invention relates to a solid-solid, solid-liquid, liquid-liquid batching device suitable for chemical industry, chemistry, environmental protection, biology, medicine, food, beverage and other fields, especially a precision chemical reagent preparation device, that is, a precision chemical reagent preparation device. Reagent preparation instrument. Background technique: [0002] At present, the commonly used reagent preparation devices mainly include the following types: [0003] The first is to use a metering pump to inject a large amount of liquid in the chemical industry. Chinese patent CN2072436 discloses a "quantitative liquid dispenser". It is composed of a sealed corrosion-resistant liquid distribution tank, a liquid inlet on the upper part of the tank, a liquid volume controller, an exhaust hole, a liquid discharge port and a valve on the lower part of the tank. Inertia or stirrer can stir evenly, and then the medicine solution with fixe...

AI Technical Summary

Problems solved by technology

However, the dosage is relatively small, inflexible, and the precise concentration cannot be fed back in real time, and solid-liquid preparation cannot be realized

[0005] The above two dispensers are only suitable for liquid-liquid preparation

[0006] The third is to weigh the water and the solid separately, and then add the solid to the water manually. It is very accurate, but it is labor-intensive, the calculation is complicated, and experience in preparing reagents is required.

[0007] The fourth is to use mechanized large hopper feeding, but it is imprecise, such as preparing sand and lime
